Abstract

Knowing the prevailing climate patterns is extremely important due to its numerous applications in different economic segments. Rainfall was the climatic element chosen for analysis due to its variability in time and space. Daily rainfall data from 1976 to 2019 were used in the municipalities of Campo Mourão and Maringá. The objective of the work was to compare and quantify the daily, monthly, seasonal, annual and interannual precipitation in order to know the determining patterns, through descriptive statistics. To verify the existence of a trend in the annual and monthly series of maximum precipitation, total precipitation and the number of rainy days, the Mann (1945) and Kendall (1975) test was used for both locations. Both municipalities summer and spring are the rainiest season. Maringá stood out with the highest total value of rainy days when compared to Campo Mourão, however Campo Mourão has a greater amount in the total accumulated precipitation. In the trend analysis only the maximum annual precipitation of Campo Mourão, a negative trend was recorded. Regarding the number of rainy days for each month, there was a negative trend only in Maringá in September. In the others, trend analysis scales, results with no significance greater than 5% were not obtained.analysis.
